Abstract excerpt
The design of beta-glycosidases with planed substrate specificity for biotechnological application has received little attention. This is mostly a consequence of the lack of data on the molecular basis of the beta-glycosidase specificity, namely data on the energy of the noncovalent interactions in the enzyme-transition state complex. In an attempt to fill this gap, site-directed mutagenesis and enzyme...
